not avoided, will result in death or serious injury.
Warning
 Always ensure compliance with relevant safety laws and
standards.
All work must be carried out in a safe manner by a qualified person in
compliance with applicable national regulations.
 This product is class A equipment intended for use in an industrial
environment. There may be potential difficulties in ensuring
electromagnetic compatibility in other environments due to conducted
or radiated disturbances.

(Set Do not install the product unless the safety instructions have been read
pressure) and understood.
 This product is pre-set at the factory and must not be dismantled by
-13.3 kPa
the user. Contact your local SMC office for advice.
1.0 MPa -101 kPa
 Ensure, when installing this product, that it is kept clear of power lines
to avoid noise interference.
0.005 to -1.3 to
 Ensure that load surge protection is fitted when inductive loads are
0.9 MPa -80 kPa
present (i.e. solenoid, relay etc.).
3.2 Environment
1)
 Do not use in an environment where corrosive gases, chemicals, salt
water or steam are present.
 Do not use in an explosive atmosphere.
 Do not expose to direct sunlight. Use a suitable protective cover.
 Do not install in a location subject to vibration or impact. Check the
product specifications.
 Do not mount in a location exposed to radiant heat.
3.3 Piping
 Before piping make sure to clean up chips, cutting oil, dust etc.
IP65
 When installing piping or fittings, ensure sealant material does not
enter inside the port. When using seal tape, leave 1 thread exposed
on the end of the pipe/fitting.
 Tighten fittings to the specified tightening torque.

6 Pressure Setting and Output Monitoring
 Set Output Pressure
Caution
Command
Note) nn is limited to integral values from 0 to 1023.
 Increase setting for output pressure
Caution
Command
Note) When set data nn is >= 1021, the value is set as nn=1023.
 Decrease setting for output pressure
Command
Note) When set data nn is <= 2, the value is set as nn=0.
 Request for set data
Caution
Command
 Request of output pressure data
Command
Pressure setting can be done by sending input data using 10 bit as F.S.
to the electro-pneumatic regulator through the master PLC.
